IMPROVED SIFTING -MACHINE.

`TO ALL WHOM IT MAY 'CONCERN Be it known that I, JOHN JOSEPH RINK, ofthe city 4of `Brooklyn,`in the county ofrKing's, inthe State of N ew- York, have invented a new and useful Machine for Levigating and Sifting Glodded Flour or other substances;

and I do hereby declare that the following is afull and exact description thereof, reference being had to the i accompanying drawings and to the letters of reference marked thereon, and of which-#- Figure I is a transverse section. Figure II represents a cross-section lengthwise. il Figure III is the frontal, lFigure IV is the profile view, (with partial cross-section.)

The nature of my invention consists in the construction of a machine which will restore to` their former 1 i uniformity of pulverization, all flour, meal, or other ground or powdered substances, whichnby dampness, by i l tight packing, prolonged storage, or any other reason, have become elodded or lumpy, and require, consequently,

I renewed labor, costs, and trouble in performing a process of restoration which my machine will do quickly, cheaply, and thoroughly.

' To enable-those skilled in the art to understand and use my invention, I shallproceed'in describing the construction and operation of my machine, and refer td the accompanying drawings and their corresponding numbers and letters.,

The barrel b containing the clottcd substance is placed upon the platform c, and firmly secured thereon by strap-work t'h. Through the means of the levers d d @and-as shown by dotted lines el czysaid platform c can be clapped down so as to facilitate the handling of the barrel. The latter being well strapped en,`is now swung easily upon the frame a, viz, the top of the machine and such through elevator e, which isa-ttached to the shaftf, and worked by the pulleys g g. The barrel thus becomes landed upon frame a, head downwards,

and the top, now bottom, board can be removed as far as deemed necessary for letting the contents enter the funnels z' t'. In Figs. II and IV, these funnels ii appear closed. They can beshut or opened, either` wholly or partially, as desired, b y the means of the handles 7c cr 1c2 7c3, which I .have designated in `different shapes for their being chosen accordingly, cr being regulated byscrew Z, k2 7c3 yby the toothedybars in shape mor n. Next to` the funnel-mouth I have placed a grate, o, the bars of which are made round and of iron. The fly-,wheel zu (con' sequently the machine) being started, this grate o moves to and fro audthus reduces thelumps or clods to fragy ments which pass through interstices of the bars of the gratep placed beneath g, and being attached to theimain framework,jconsequently remain stationary. Said gratep has its bars laid closer toeach other than those of` grate o, 'sothat the flour shovelled and rubbed between said two gratespasses already well powdered to the sfter g.

The bars of gratep can be formed diiierently, as shown in Fig. II. The sitter q will `be perceived to be placed underneath grate p, also moves like grate'o, but in another direction, and sieves the ilour into trough 1', 'which rests in. a decliningplane, between the iron suspendersj t, which are connected with two India-rubber bands a: x, (one on each side,) for the purpose of making the gratos and sifter return again to their proper positions. This troughvis rocked to and fro by the pin-block v. In this manner the siftcd Hour passes fromrsaid `trough r intoV the receiving-vessel. In'order to obviato loss of material, the spaces between the funnels z and the` .grate o have been guarded by the boards .9 s; The tineness of theA texture of sii'ter q stands in accordance to`tl1at .of

the material submitted to the process of disclodding.4 It will thus be apparent, that the automatical movement ofthe grate o upon and along the immovable grate p, the difference'in the interstices ofthe bars of thc respect` ive gratos op, the motion ofthe sifter g, and the rocking arrangement of trough r, will separato and crumble the clods, restore the our, etc., to its former condition, and transfer it in its desired state of uniform iineness from the barrel b through the machine to the receiving-vessel.

What I claim `new as my invention, and desire to secure by Letters Patent, is- 1. The arrangement ofthe elevator e, `with the strap-work L t, for the purpose specified. 2. Thecoinbination and arrangement oi' the' grates o p, and the sifter g, for the purpose specified.

3. The construction and arrangement of the levers c kl lc k2, regulating `the shutting or opening ofthe funnels z' z', for the purpose as stated and described.
